This equipment includes upper casing 1, lower floor's casing 2, sets up upper trommel sieve 3 in upper casing 1, sets up lower floor's trommel sieve 4 in lower floor's casing 2, sets up respectively in connecing material conveyer 5, transmission 6 and deformation device 7 of the below of upper trommel sieve 3 and lower floor's trommel sieve 4, wherein: first feed inlet 31 and material receiving opening 32 have been seted up respectively to the both ends of upper drum sieve 3, and second feed inlet and bold packing material discharge gate 41 have been seted up respectively to the both ends of lower floor's drum sieve 4, and the sieve mesh diameter of the first half section of lower floor's drum sieve 4 is less than the sieve mesh diameter of the latter half section. The material receiving and conveying device 5 on the upper layer is provided with a kitchen waste discharge hole 51, and the material receiving and conveying device 5 on the lower layer is respectively provided with a plastic packaging material discharge hole 52 and a paper packaging material discharge hole 56. The inner walls of the upper layer rotary screen 3 and the lower layer rotary screen 4 are provided with a plurality of guide blades 33, and the plurality of guide blades 33 are distributed at equal intervals along the spiral direction. The guide vanes 33 serve to mix the materials while conducting the materials. During operation, after the garbage is fed through the first feed inlet 31 of the upper drum screen 3, under the driving of the transmission device 6, the upper drum screen 3 rolls, and under the driving of the guide vanes 33 which are spirally distributed, the garbage is lifted and thrown off, finally, the kitchen garbage with small size, such as food residues, in the garbage is separated out under the action of the upper drum screen 3 and falls to the material receiving and conveying device 5, and then the kitchen garbage is conveyed to the kitchen garbage discharge port 51 to be discharged, and the kitchen garbage discharged from the kitchen garbage discharge port 51 can enter other treatment facilities for centralized treatment. After the first screening is completed through the process, the kitchen waste is separated, and the residual waste is driven by the guide blades 33 in the upper layer drum screen 3 to move to the material receiving port 32, then sequentially enters the deformation device 7 and the lower layer drum screen 4, and continues to screen the plastic packaging materials and the paper packaging materials.
The deformation device 7 is designed according to the characteristics of plastic and paper packaging objects, and because the plastic and paper packaging objects are effectively extruded and deformed, the paper packaging objects are irreversibly deformed, the diameter of the paper packaging objects is increased after deformation, and the diameter of the plastic packaging objects is unchanged after deformation.
